Separation of high-purity natural phytol from byproduct of silkworm excrement extract by molecular distillation

Natural phytol which is a flavor of natural food can be also used in the synthesis of medicine like vitamin K1, health products, functional foods and cosmetics, etc. In this study, preparation of high-purity natural phytol from byproduct of silkworm excrement processing was carried out by using secondary molecular distillation process. Natural phytol of 98 percent purity and above was observed as a result of process conditions optimization.
